Summary of Contents for Pass Laboratories XP-30

  • Page 1 XP-30 Owner’s Manual Rev. 0 - Oct 3, 2011...
  • Page 2 We want you to anticipate listening to your entire record collection, again and again. As part of the process in developing the XP-30 we began by uniformly upgrading the playback systems of our listening group. We do not do AB or ABX testing – our people live with prototypes as long as they like in their own system, and only one component gets changed at a time.
  • Page 3 The XP-30 is a modular preamplifier consisting of one control / power supply chassis and additional gain chassis, each containing the analog circuits of a single channel. The XP-30 is meant to typically be used as a two-channel product, but you can use the control chassis to serve up to six channels.
  • Page 4 Like Nelson, Wayne looks at parts and sees not applications but potentials. The XP-30 uses a new and more advanced version of the gain modules that have been popular in Pass products for the last ten years. It has lower distortion and wider bandwidth than its predecessor and also features a dramatically higher input impedance.
  • Page 5 On a more sober note, please read and understand the operational instructions and safety issues associated with this product. All of us at Pass Laboratories put great effort into building a soundly engineered and superbly performing rugged product of lasting durability and value. We understand that things occasionally go wrong, but we are here to support you if that happens.
  • Page 6 Do not plug in the power cord yet. Second Place the components that comprise the XP-30 in the locations where you plan to use them. They don't need a lot of ventilation, but a little is helpful. On the rear of each control chassis are two identical DIN-25 sockets in parallel with one another.
  • Page 7 6 with the letters L (left) and R (right) as suffix’s to the level setting. The XP-30 has a single pair of binding posts on the power-supply / control chassis which are labeled “Ext. Amp Turn-on”. A 12-volt DC signal is available at these...
  • Page 8 If you have a question, please contact the Pass Laboratories factory. Specific to Pass Laboratories power amplifiers is the requirement that the power amplifier be placed in standby from it’s front panel control before using the remote turn on function.
  • Page 9 Grounding: Adequate precautions should be taken so that the grounding provisions built into an electrical product are never defeated. Power Cords: Pass Laboratories provides a high quality power supply cord that meets all legislated requirements for the market in which the product was originally sold.
